Background Since New Zealand adopted
proportional representation ahead of its
1996 general election,
party switching (or
waka-jumping) had been criticised for disturbing the proportionality of parliament as determined at a general election. Previously, party dissidents had simply served as independents. However, in the
44th Parliament (from 1993 to 1996) and
45th Parliament (1996 to 1999), 22 MPs defected to other parties. The
Alliance, a party which had been formed by
Jim Anderton's defection from
Labour to
NewLabour in 1989 and had been disadvantaged by the defection of
Alamein Kopu in 1997, supported tighter controls on party switching. The Labour Party was also in favour. Deputy leader
Michael Cullen introduced legislation to forcibly expel party switching members in October 1997, but a 5–5 split on the electoral law committee prevented the bill from progressing further. The two parties jointly campaigned at the 1999 election for tighter controls on party switching which were soon progressed by the new
Labour–Alliance coalition government. In the 1999
Speech from the Throne, the
Governor-General announced on behalf of the new government:My government recognises that there is deep public concern with a number of aspects of the operations of our political system in recent years. In particular, my government believes that the public is not prepared to countenance any repetition of the level of defection by Members of Parliament from their parties which has occurred in the last two parliaments. Accordingly, legislation will be introduced to provide that, for this and the next parliament at least, such a practice will be outlawed. Members of Parliament will, therefore, be reminded of the obligations they have to the people of New Zealand when they seek and gain election under the banner of a political party. —
Michael Hardie Boys,
Speech from the Throne (1999)
Legislative history was a leading figure in the development of the Electoral (Integrity) Amendment Act 2001. The described legislation—the Electoral (Integrity) Amendment Bill—was introduced by associate justice minister
Margaret Wilson the next day, 22 December 1999, and sent to the justice and electoral committee in a 64–55 vote. One Labour member was absent. It was the first bill debated in the new parliament and her speech on the bill was Wilson's first given as a newly elected MP. Labour, Alliance,
New Zealand First, and
United members were in support, while
National,
ACT, and
Green members were opposed. Speaking against the bill, National MP
Simon Upton acknowledged the bill's attempt to give greater weight to parliamentary proportionality over other considerations but stated: "that is, of course, not an absolute principle. The 5 percent threshold, for one, and the prospect of a by-election, for another, mean that proportionality is compromised... We have to weigh [proportionality] up against some other principles [such as] the importance of allowing political parties to evolve and allowing electoral systems to evolve [and] the freedom of speech and conscience." Legal advice from the
solicitor-general John McGrath said trying to strengthen the bill to secure non-voluntary resignations might cause it to no longer be consistent with the
New Zealand Bill of Rights Act 1990. The outcome was that party leaders would be able to write to the Speaker with the support of two-thirds of the party's caucus, forcing the expulsion of a member. The second reading was completed under urgency on 20 December 2001 (officially recorded as 18 December in
Hansard); the committee stage (wherein the amendment negotiated with New Zealand First was officially agreed) and third reading were held immediately afterwards. Speaking in the debate, Green co-leader
Rod Donald addressed New Zealand First leader
Winston Peters' apparent change of heart by quoting one of Peters' old press releases: in 1996 he had said "Members of Parliament joining New Zealand First or any other political party without resigning and seeking a new mandate is consistent with constitutional precedent. MPs have to be free to follow their conscience. They were elected to represent their constituents, not swear an oath of blind allegiance to a political party." The final vote was 64–54. Two ACT members were absent and the sole United member
Peter Dunne withdrew his earlier support. Despite the strengthening of the bill in the committee stage, almost immediately MPs found ways to work around its provisions. The Alliance fractured in 2002 over New Zealand's involvement in the
War in Afghanistan and Anderton formed a new party, the
Progressive Party. To avoid triggering the legislation he had endorsed, Anderton nominally remained leader of the Alliance within parliament even while campaigning as the leader of the Progressives; he struck a deal with
Laila Harré, who led Alliance members who did not follow him, wherein she would not "publicly lay claim" to the Alliance leadership. National leader
Bill English called the arrangement deceitful; Anderton denied accusations of waka-jumping because he still supported the government. Prime minister
Helen Clark responded by calling an early election. In the subsequent term, Labour MP
Tariana Turia resigned from her party and the parliament in 2004, forcing
a by-election where she was re-elected as a candidate of the
Māori Party. ACT attempted to expel list MP
Donna Awatere Huata in 2003; after a 10-month legal battle the
Supreme Court declared in 2004 Awatere Huata had "distorted, and is likely to continue to distort, the proportionality of political party representation in Parliament as determined at the last general election" and permitted her expulsion to proceed. It was reported that National threatened
Maurice Williamson with the Act in 2002 and 2003, but it was conceded that this was unlikely in practice.
Expiration and attempted reinstatement The Act expired at the
2005 New Zealand general election as its sunset clause came into effect. The reintroduction of the Act was part of the confidence and supply agreement formed between Labour and New Zealand First after that election. A replacement Electoral (Integrity) Amendment Bill was moved on behalf of the deputy prime minister
Michael Cullen on 6 December 2005; it was sent to the justice and electoral committee in a 61–60 vote. Labour, New Zealand First,
United Future and the Progressives were in favour; National, the Green Party, the Māori Party and ACT were opposed. The new bill was proposed without an expiry date. A legal opinion from
solicitor-general Terence Arnold reviewed the bill's compliance with the
New Zealand Bill of Rights Act 1990 (BORA). Arnold's view was that the bill made
prima facie infringements on the rights of members of Parliament to
freedom of expression and
freedom of association. However, he stated that arguments made by the Supreme Court the previous year meant although "it can be argued that the Bill should protect 'legitimate dissent' by members in respect of their parties and, to the extent that it does not, it is BORA inconsistent, on the basis of
Awatere Huata, the better view is that the Bill is consistent with, and does not breach, BORA." After select committee consideration of the bill, United Future removed its support for the bill and the attempt to reinstate the Act failed. While no electoral integrity laws were in place, party switching resumed, but less frequently than the pre-1999 period. List MP
Gordon Copeland, who had been party of the government-supporting
United Future sat as an independent from 2007 and began supporting the opposition National Party.
Te Tai Tokerau MP
Hone Harawira resigned from the Māori Party and Parliament in 2011, forcing and winning a by-election under the new
Mana Movement. There were also three expulsions:
Taito Phillip Field (2007) and
Chris Carter (2010) were expelled from Labour and
Brendan Horan (2012) from New Zealand First. All of the expelled MPs remained in Parliament until the end, or near-end in Carter's case, of their terms in Parliament; Field and Horan unsuccessfully sought re-election. Public opinion appeared to be in favour of reintroducing electoral integrity laws, at least for list MPs. A 2013 public opinion poll found, that 76% of New Zealanders opposed list MPs staying in Parliament if they leave their party. == Electoral (Integrity) Amendment 2018 ==
